摘要：

With the emerging of the third generation (3G) wireless technology, digital media, like image and video, over wireless channel becomes more and more demanding. In this paper, the measure metrics for the wireless image is proposed and a Qos-guarantee error control is presented, combining UEP with Forward Error Correction (FEC) and Automatic Repeat reQuest (ARQ), aiming to high quality image transmission with short delay and little energy. Simulation results show that our scheme can achieve good reconstructed image with few retransmission times and small bit budget under different channel conditions, which can reduce the energy consumed in the network interface.
